1 12 Claims.

This invention relates to counters, and in general has for its object the provision of an integrating counter for effecting a group count of a plurality of events or operations such as for example the movement of a plurality of objects past a given point or station.

Counters for this purpose are desirable in many industries. Stationary, for example, is sold in bundles designated as reams, there being 480 sheets to a short ream, 500 sheets to a long ream and 516 sheets to a printers ream. The sheets are continuously delivered from a cutter or a press and although there are counters available for effecting a progressive count thereof, the

problem is to integrate this count into counts 3;

representing reams and/or to operate some sort of translating device such as a signal either on the group count or on a predetermined individual count preceding each group count.

More or less the same problem is presented when it is desired to stack shingles in bundles each containing a predetermined and selected number of shingles, or in numerically segregating any other objects into groups.

More specifically the object of this invention is the provision of an integrating counter comprising: a control circuit including a power release relay and responsive to an external translating device, which in turn is responsive to the movement of each object of a plurality of objects to y be counted in groups of a preselected number; a locked torque, shaded pole, reversible type motor having a rotor, a main Winding arranged to be continuously energized during the entire counting operation, and a pair of shading coils arranged to be alternately short-circuited to reverse the direction of rotation of said rotor at each group count; a power escapement or release mechanism associated with the shaft of the motor and operable in response to the power release relay for permitting said shaft to rotate in predetermined increments; a pair of rotatable dials each graduated in 100 units, one of said dials being designated as a units dial and the other as a hundreds dial; a pair of gear trains driven by said motor and in driving relation with said dials, there being a diiierential in the gear ratios of these gears such that when the units dial has completed one revolution the hundreds dial has rotated through only 99 of its 100 units; one fixed and one adjustable switch cam mounted on each of said dials for rotation therewith; a pair of stationary switches associated with each of said dials and located in the path of its cams so movement thereof; and an electric circuit including said camactuated switches, a Vernier switch periodically closing in response to the rotation of said shaft, a set of interlocking relay switches, one of said switches being operable to alternately short-circuit said shading coils and open and close a controlled circuit in response to a preselected sequence of operation of said cam actuated switch, said controlled circuit being arranged to .be connected with any desired external translating device such as a conventional magnetic counter, bell, light or relay switch.

The invention possesses other advantageous features, some of which, with the foregoing, will be set forth at length in the following description Where that form of the invention which has been selected for illustration in the drawings accompanying and forming a part of the present specification is outlined in full. In said drawings, one form of the invention is shown, but it is to be understood that it is not limited to such form, since the invention as set forth in the claims may be embodied in a plurality of forms.

Fig. 8 is a wiring diagram showing the electrical circuit associated with and forming a part of the counter shown in the above figures.

Figs. 9, 10, 11 and 12 are front elevations of the counter panel progressively showing the condition of the dials in counting from zero to the predetermined count of 710 and back again to the count of 1420.

Figs. 9a, 10a and. 11a are schematic wiring diagrams showing the condition of the electrical circuit corresponding to the positions of the dials shown respectively in Figs. 9, 10 and 11.

As shown in the figures above described, my counter comprises an instrument panel 1 provided with suitable screw holes 2 at its corners as to be periodically closed in response to the 68 for fastening it to a suitable instrument case,

not shown. Mounted on the rear face of the panel by brackets 3 and 4 is a locked torque, shaded pole, reversible type motor 5 of conventional construction. The motor 5 includes a rotor 6 provided at its ends With axially aligned drive shafts 1 and 8 terminating respectively in fourthread worms 9 and H. As diagrammatically illustrated in Fig. 8, the motor 5 also includes an electromagnet i2 provided with a field coil i3 and shading coils M and I5.

Fastened to the panel by screws l5 are a pair of parallel sleeves I1 and I8 (see Figs. 3 and 4), and mounted in each of these sleeves are a pair of bearing bushings l9 and 2|, the bushing I9 extending forwardly through the panel 'I. Journaled in the bearings l5 and 2| of the sleeve 11 is a shaft 22 and similarly journaled in the bearing bushings of the sleeve 18 is a shaft 23. Fastened to the shaft 22 by a set screw 24 is a worm gear 25 having 100 teeth and arranged to mesh with the four-thread worm 9 and similarly fastened to the shaft 23 is a worm gear 26 having 101 teeth and arranged to mesh with the fourthread worm Since the gear 25 is provided with one hundred teeth and its associated worm 9 is provided with four threads, the gear ratio between these two members is 1 to 25. In other words, each complete revolution of the worm 9 serves to advance the worm gear 25 by four teeth or a quarter revolution of the worm serves to 1.

advance the worm gear 25 by one tooth. The diameter of the worm gear 23 should be sumciently greater than the diameter of the worm gear 25 to result in a gear ratio between these two members of 100 to 99. As a result of this gear ratio differential, the worm gear 23 will complete only 99/ 100 of a revolution for each complete revolution of the gear '25.

Fastened to each of the shafts 22 and 23 immediately forward of its associated bearing bushing [9 is a spacing washer 21. Journaled on the shaft 22 immediately forward of its spacing washer 21 by means of a flanged bearing bushing 28 is a units dial 29, the dial 29 having a press fit with the bushing 28. Threaded over the forr ward end of the shaft 22 is a knurled lock nut 3| for locking the dial 29 to the shaft 22 in any desired angular position relative thereto. Similarly journaled on the forward end of the shaft 23 by a flanged bushing 32 is a hundreds dial 33 arranged to be locked to the shaft 23 in any :desired angular position relative thereto by a knurled lock nut 34. Provided on the faces of each of the dials 29 and 33 respectively are continuous scales 35 and 36, each divided or graduated into onehundred units, the scale 35 being designated for purposes of convenience as the units scale :and the scale 33 being designated as a hundreds scale. The scale 35 is therefore a function 'of the scale 35 and although for purposes of illustration the decimal system has been used, any other system can be resorted to so long as one scale is a predetermined function of the other scale.

Fixed to the back of the units dial 29 is a cam pin 31 having a rounded end. Adjustably mounted on the rear face of the dial 29 is a campin 38, this cam being mounted on a peripherally adjustable slide 39 provided with pins 4| arranged to travel ina circular channel42 formed in the back face of the dial.

Attached to the forward side of the slide 39 by a screw 43 is aplate 44 overhanging the outer periphery of the dial. Threaded in the slide 39 is a-set screw 45 for affixing the slide to the dial in any predetermined angular position relative thereto. From an inspection of Fig. 3 it is to be noted that the cam pin 39 is radially offset with respect to the fixed cam pin 31, and from an inspection of Fig. 2 it will be noted that it can also be adjusted to assume any desired angular position relative to the cam pin 31.

The dial 33 is similarly provided with a fixed cam pin 45 and with a peripherally adjustable cam pin 41 mounted on a slide 48, a set screw 49 being provided on the slide for fastening it in any predetermined selected position relative to its dial 33. Mounted on the back of the panel at either end thereof are microswitches 5| and 52, these switches being shown in dotted line in Fig, l, and the switch 5| being shown in full line in Fig. 5. As shown in Fig. 5, each of these microswitches includes an actuator arm 53 pivoted to the switch body and provided on its free end with a cam follower roll 54. The cam follower rolls extend through openings formed in the panel and are disposed in the path of the fixed cam pins 31 and 45. The microswitches 5| and 52 are of conventional construction and provided with spring means for biasing their actuating arms 53 outwardly in the paths of the cam pins 31 and 45. As a result of this construction, whenever either of the cam pins passes over its associated cam follower roll 54 the corresponding microswitch will be closed.

Inscribed on the base of the panel adjacent each of the dials 25 and 33 are fiducialmarks 55 and51 respectively, the location of the microswitches 5| and 52 relative to their associated cam pins 31 and 45 being such that when these pins serve to close their associated microswitches 5| and 52 the zero positions of these dials are in registration with their respective fiducial marks 55 and 51.

Fastened to the back of the panel behind the dial 29 is a conventional inicroswitch 58 in all respects similar to microswitches 5| and 52 and including a cam follower roll 59 (see Figs. 1 and 3). The roller 55 extends through a hole 6| formed in the panel and is located in the locus of the peripherally adjustable cam pin 38. It will therefore be seen that whenever the cam pin 33 passes over the cam follower roller 59 the switch 58 will close momentarily. Similarly mounted on the panel behind the dial 33 is a conventional microswitch 62 provided with a cam followerroll 53 as shown in dotted line in Fig. l. The cam follower 53 extends through an opening in the panel I and is located in the locus of the adjustable cam pin 41 so that whenever the cam pin 41 engages this roll the switch 62 will be closed momentarily.

Mounted on the back side of panel I beneath the worm II is a conventional electromagnet power relay 65 including a relay coil 66 and an armature 61 pivoted to the relay body by a pin 53. Fixed to the armature 61 at substantially right angles thereto is a switch actuator 63. Carried by the relay are a pair of spaced switch contacts 12 and 13 and an intermediate contacto-r 14 carried on a spring finger 15. With the switch actuator 69 in its upper position as shown in Fig. 8 the contacts 12 and 14 are in engagement with each other with the contact 13 disengaged from the contact 14. Upon depression of the contactor 69 due to the inward movement of the armature 61 when the relay coil 66 is energized, the actuator 69 closes the contact 14 on the contact 13 and breaks the contact between the contacts 12 and 14.

' Formed on or secured to the free end of the armature 6! is an escapement or power release finger I8 extending upwardly to a point immediately adjacent the shaft 8 and disposed between two longitudinally spaced collars I1 and "I8 fastened to the shaft 8. Carried by the collar II are four inwardly extending escapement studs I9 spaced 90 apart with respect to each other and similarly carried by the collar I8 are four inwardly extending studs 8| also spaced 90 apart with respect to each other and angularly offset 45 with respect to the angular location of the studs I9. Normally the spring finger holds the power escapement finger I8 outwardly in the position shown in Fig. 1, the finger I6 then being located between two adjacent studs I9. When the relay coil 68 is energized, the finger I8 moves to the right (as viewed in Fig. 1) to a position between two of the adjacent studs 9|. This mechanism therefore serves as a clutch, escapement or power release for permitting the shafts I and 8 to rotate only through A; of a revolution when the finger I6 is in either of one of its two positions, this being more clearly illustrated in Fig. 7. In this figure, the finger I6 is shown stopped by one of the studs I9. Upon the inward movement of the finger I8 when the power relay coil 66 is energized, it will move to a position between the two adjacent studs 8| and after the shaft has moved through A; of a revolution it will be stopped by the adjacent stud 8|. --As previously described, of a revolution of the shafts I and 8 will cause the worms 9 and II to displace the gear through one tooth and the gear 26 through somewhat less than one tooth.

Mounted on the switch 5| is a conventional interlocking reversing relay generally designated by the reference numeral 85 (see Fig. 5), and including a pair of relay coils 88 and 81, a pair of armatures 88 and 89, and a double throw therewith are interlocking arms 99 and I0I.

When the relay coil 86 is energized its armature 88 moves inwardly and the arm 93 moves outwardly thereby moving the switch actuator 94 outwardly to close its contact 95 on the outer contact 98. In accordance with well known operation, the interlocking arm IOI moves behind the end of the arm 99 so as to lock the relay in this position until such time as the armature coil 8! has been energized. Upon the occurrence of this event the armature 89 will move inwardly to release the arm IOI from beneath the end of the arm 99 thereby permitting the switch actuator 94 to move inwardly to open the contacts 95 and 98 and to close the contact 95 on the contact 91.

Also mounted on the switch 85 adjacent the contacts 95, 9! and 98, but insulated therefrom, are a pair of contacts I02 and I03 the back ends of which are shown in Fig. 1 and which are diagrammatically indicated in Fig. 8. These contacts are adapted to be brought into engagement with each other in response to the downward movement of the actuator 94. Similarly mounted on the switch 52 is a conventional reversing relay generally designated by the reference numeral I04, including a pair of relay coils I05 and I 06, a pair of armatures I01 and M8, a pair of interlocking arms I09 and II I, a pair of contact points H2 and I I3, and a switch actuator movable in response to the movement of the armature I 01 for closing the contact point II2 on the contact point II3 (also see Fig. 8);

As diagrammatically indicated in Fig. 8, the movable contact points of the switches 5| and 58 are comiected respectively through leads H5 and H6, and a common lead III, with the contact point I2 of the power release relay 65. The fixed contact point of the switch 5| communicates through a lead II8 with a vernier switch generally designated by the reference numeral H9, and through leads II 9a and I20 with the movable contacts of the switches 52 and 82, respectively.

The fixed contact of the switch 52 communicates through a lead I2I with one of the terminals I22 of the relay coil I06 and with one of the terminals I23 of the relay coil 85. The fixed terminal of the switch 62 communicates with one end of the relay coil I05 through a lead I24. The fixed terminal of the switch 58 communicates through a lead I25 with the contact point II3 of therelay switch I03, the other contact point of the switch I03 communicating through'a lead I28 with one of the terminals I2I of the relay coil 87. The relay coils 86 and I05 are connected in parallel through the leads I28 and I29, the terminals |3I and I32 of the relay coils 86 and '81 being connected to the lead I28.

The lead I28 communicates with one of the terminals I33 of the motor field coil I3, the other terminal I34 of this coil communicating through alead I35 with the contact I02 of the switch 9|. The coil terminal I34 also communicates through the lead I 35 with one of the terminals I38 of an on-and-ofi switch generally designated by the reference numeral I3? and mounted on the lower edge of the panel I. The other contact point I38 of the switch I3I communicates through a lead I39 with a lead I4I communicating with the terminal I33 of the coil I3 and also with the terminals I42 of a conventional magnetic counter I43. As shown in Fig. 2 the counter I I-3 is mounted on the panel I with its face visible through a window I44 formed in the panel. The other terminal I45 of the magnetic counter communicates through a lead I 48 with the terminal I3 associated with the switch of the power release relay 65. 1

The on-and-oif switch I31 serves to establish communication between the device above described and the positive and negative terminals of a power line generally designated by the reference numeral I41. Connected to the terminal I53 of the relay switch is a lead I48 communicating with the positive terminal I49 of a translating device such as a bell, light, switch or conventional magnetic counter to be actuated under the influence of the circuit above described. The negative side of any device of this character can of course be connected to the negative side of the line I48 to complete the circuit. Connected to one of the terminals I5| of the coil 66 of the power release relay 65 is a lead I52 communicating through a lead I53 with the contact I4 of the switch associated with the relay 65 and communicating with the terminal I34 of the coil I3.

' The other terminal I54 of the coil 88 communicates through a lead I55 with the positive terminal I56 of any translating device such as a switch directly or indirectly operable under the influence of the objects to be counted in groups in accordance with the object of my invention. The other terminal of such translating device can of course be connected with the negative side of the power line I41 to complete the circuit.

. The Vernier switch I19 interposed between the switches 5| and 52 is a microswitch of the same type as the switches 58 and 62 and includes a cam follower roll I51. Detachably mounted on the shaft I by a set screw I58 is a collar I59 extending radially from this collar is a cam pin I6I in alignment with the roll I51, the roll I51 being located in the locus of the pin. As a result of this structure the switch II-9 assumes its closed position momentarily only once during each complete revolution of the shaft 1. It should here be noted that this switch is actuated directly in response to the rotation of the shaft 1 whereas the cam pins 31, M, 46 and 41 are driven indirectly through the gear trains constituted by the worms and worm gears associated with the shafts I and 8. Therefore the interposition of the Vernier switch IIS between the switch BI and the switches 52 and 62 en sures that the circuits including the leads I2I and I24 will be energized directly in timed relation with the rotation of the shaft regardless of inaccuracies or back-lash in the gear trains.

Operation For the purposes of illustrating the operation of the device above described. let it be assumed that it is desired to effect a count of 710 and each succeeding multiple thereof. More specifically, let it be assumed that it is desired to energize the controlled translating device connected with the terminal I49 each time that the controlling transclip 39 of the unit dial is then adjusted and locked so that its fiducial mark 39a lies over the number V I of the scale 35 and similarly the clip 48' of the dial 33 is adjusted and locked so that its fiducial mark 48a lies over the number 7 of the scale .36. Also at this time the Vernier switch I I9 should be closed by so adjusting the collar I59 that its cam pin I6I is in direct engagement with the cam follower roll I51. The on-and-ofi switch I31 can then be closed whereupon the circuit will assume the condition shown in Fig. 8. Since in this condition of the circuit the relay coils 86 and I06 are energized, the armatures B8 and I08 of the relays 85 and I04 will be in their closed position and held in these positions by the inter locking arms IOI and III of their associated relays. Since the contact 96 of the reversing relay 85 is now in engagement with the contact 61,

the shading coil I4 is short circuited and consequently the motor 6 will rotate in a counterclockwise direction whenever permitted to .do so by the escapement mechanism associated with the power release relay 65. Since the external translating device connected to the terminal I49 is under the control of the switch actuator 94 of the relay 85 the condition of this translating device will remain unchanged until the armature 88 orthe relay B ispermittedto move upwardly Fig. 9a.

and this can occur only when the relay coil 8! is energized. However, the coil 81 is under the control of the switch I03 of the relay I04 and consequently the upward movement of the armature 88 will occur only when the coil I05 of the relay I04 is energized. From an inspection of Fig. 8 it will be seen that the coil I05 can be energized only provided that the switches 5I, H9 and 62 are all simultaneously in their closed positions. relay is energized under the influence of the controlling translating device connected to the terminal I56 and which in turn is responsive to the movement of the objects to be counted, the movable contact I4 will close on the contact .13 thereby closing the circuit including the magnetic counter I43 and opening the circuits including the switches 5I 52,, 58, 62 and II9. When the external control circuit associated with the terminal I56 is broken, the movable contact .14 of the power release relay switch 65 will return to its normal position in contact with the contact point I2.

During this single complete cycle of operation of the power release relay its associated finger 16 will have moved first to the right as shown in Fig. l to thereby permit the shafts 'I and 8. to rotate through of a revolution and then to the left to its original position thereby to permit the shafts to rotate through an additional of a revolution to complete a single count. Simultaneously the counter I43 will have effected a single count, this being indicated on its face. The dials 29 and 33 will each have moved one unit counter-clockwise, it being borne in mind that the gear ratio between these two dials is 100 to 99. Upon the initial movement of the shafts l and 8 the switches 5I, 52 and H3 will open and although this serves to deenergize the relay coils 86 and I06, their armatures 88 and I08 will nevertheless remain in their closed positions due to the interlocking action of the arms MI and III. The motor 6 will therefore continue to rotate in a counter-clockwise direction step-by-step in increments corresponding to A; of a revolution under the influence of each make and break of the switch associated with the power release relay 65 until the coil 81 of the relay is energized.

Referring now to Figs. 9 and 9a, it will be seen that when the units dial 29 has completed one revolution its zero mark will be in registration with the fiducial mark 56 and the switch 5I will again be in its closed position as indicated in The hundredths' dial 33 will be short one unit from arriving at its initial position and consequently the switch 52 will remain open. Although the Vernier switch H9 is closed at this point, the switches 52 and 62 are open and consequently the condition of the relays 85 and I05 is unchanged and the motor will continue to rotate in a counter-clockwise direction.

The first change taking place in the circuit serving to influence either of the relays 85 and I04 occurs at the count of 700 as indicated in Figs. 10 and 10a. At the end of this count the zero point of the units dial 26 is in registration with the zero ilducial line 56, and the fiducial line 43a of the slide 68 will be in registration with the fiducial line 5? which insofar as the circuit is concerned means that the switches 5i, H9 and 52 are closed, whereupon the relay coil 805 is energized and the switch I 63 is closed. However. at this point no currentcan flow through the relay coil 8! for the reason that at this count the switch 58 is still in its Open position. So far, all

When the coil 66 of the power release that has happened is that the armature It! has been drawn into its closed position and locked in that position by the locking arm I09 of its associated relay. Upon the completion of the count of 710 the dials and circuits are in the condition shown in Figs. 11 and 11a with the fiducial line 39a of the slide 39 in registration with the fiiducial line 56 of the panel.

The switch is now in its open position, the switch 58 is closed, and the switch 62 is in its open position. The circuit through the relay coil 81 has therefore been completed and consequently the armature 89 will be drawn downwardly and locked in its closed position by the arm 99, and the armature 88 has moved to its open position. Simultaneously with the movement of the armature 88 to its open position the switch actuator 94 has moved outwardly to break the connection between the contacts I02 and I03, to break the connection between the contacts 96 and 9'! and to close the movable contact 96 on the contact 98. This results in shorting out the shading coil 15, breaking the closed circuit including the shading coil [4, and breaking the circuit including the lead I48 and the terminal I49. The breaking of this latter circuit actuates the controlled translating device connected to the terminal I49 and which as previously stated may take the form of a counter, bell, light or any other suitable device. If a counter is used it will indicate a count of 1 whereas the counter M3 willhave-registered a total count of 710.

The motor 6 will now rotate in a clockwise direction until the first multiple of the count of 710 (1420) has been reached, whereupon the motor will again reverse so as to rotate in a counterclockwise direction. Upon each reversal of the direction of rotation of the motor the externally controlled translating device connected with the terminal I45 will be actuated. If the external translating. device is in the form of a counter it will register a count for each movement of the switch actuator 94.

During the entire operation of the device, the Vernier switch l9 closes and opens during each revolution of the shafts i and 8. The dimensions and contour of the cam pin 6| serving to actuate the vernior switch should be such that the switch remains closed for an interval of time equivalent to A; of a count. Although this switch makes and breaks once during each revolution of the shafts, this is of significance only during such periods that the switches 5|, 52 and 62 are closing. During these periods of operation, the vernier switch serves to ensure that the circuits controlled by the switches 52 and 62 are energized within a time period having no greater variation than that represented by A; of a count, regardless of minor inaccuracies in the gear trains resulting either from their manufacture or wear.

The use of a reversible motor greatly simplifies an integrating counter of this type for upon arriving at each count the sequence of operation of the switches 5|, 52, 58 and 52 is simply reversed with the consequent reversal of the sequence of operation of the relay switches 85 and H34. Any integrating counter not making use of this expedient would certainly require a greater number of dial actuated switches and would in a all probability involve other complications.
